ArnNr ADJUSTABLE DRILL OR PLOW POINT.

SPECIFICATION forming part of Letters Patent No. 265,288, dated October3, 1882.

Application filed July 10, 1882.

To all whom it may concern:

Be it known that I, CHRISTIAN E. SroNEsI- FER, a citizen ofthe UnitedStates, residing at Boonsborough, in the county of Vashington4 and Stateot' Maryland, have invented certain new and useful Improvements inAdjustable Drill or Plow Points; and I do hereby declare that thefollowing is a full, clear, and exact description ot' thesame,ret`erence being had to the annexed drawings, making a part of thisspecitication, and to the letters and iigures ot' reference markedthereon.

Figure l of the' drawings is a perspective view ofmy invention; Fig. 2,a sectional View; Fig. 3, a plan viewot' the plow-point, and Fig. 4 adetail view ot' the cap.

This invention relates to certain new and usei'ul improvements inadjustable drill or shovelplow points, and it consists in providing thesaid point with a series of square or other shaped openings, (notcireular,) through which passes a bolt connected to a cap, the said boltalso passing through a projection or head upon the under side of thecap,.whch is of'a shape similar to the opellings in the point or plow,into which it tits to prevent the cap from becoming displaced; and theinvention further consists in providing the hoot or stock with iiangesupon its outer sides, between which the point or plow is placed toprevent the lateral displacement of said point or plow.

ln the accompanying drawings, Arepresents the boot of a drill-toothhaving upon its outer sides, near the foot, iiangesB, between which isplaced the point or plow C, these flanges serving to prevent any lateraldisplacement of the said point or plow. The point or plow U is providedwith a series of square or other shaped openings, D, ot' any desiredform other than circular, to allow of the adjustment ofthe said point orplow to the depth for drilling or plowing by means of the head orprojection E upon the under side ot a cap, F, being of the same shapeand tting in the openings inthe point or plow. The cap and point or ploware secured to the boot or stock by means of a screw- (No model.)

threaded bolt, G, being rigidly connected to the cap, and passingthrough the projection or head E and boot or stock A, and held by a nut,H. The cap F prevents the dirt from filling up the openings in the pointor plow, whileat the same time the projection or head upon its underside iitting the openings in the point or plow admits of the said pointor plow being quickly adjusted to suit the convenience ot the operatorand the quality of earth upon which it is used. The openings, beingofthe form described, will prevent the point or plow from becominglaterally displaced should the anges upon 'the sides ot' the boot orstock become worn or broken.

Iam aware that it is not broadly new to use a reversible and adjustablepoint or plow secured to a.drillboot by means of a screw-bolt and nut;but my invention differs from such construction in the novelorganization and arrangement of parts, as hereinbet'ore stated,

Having now fully described my invention, what I claim as new, and desireto secure by Letters Patent, is-

1. The point or plow C, provided with openings D, ot' the formdescribed, in combination with the cap F and boot or stock A,substantially as and for the purpose specified.

2. The cap F, provided upon its under side with the projection or headE, in combination with the point or plow O, having a series ot'openings, D, and the boot or stock A, substantially as and for thepurpose set forth.

3. The boot or stock A, provided with the flanges B, in combination withthe point or plow C, having the openings D, and the cap F, having thehead or projection E, substantially as and for the purpose described.

In testimony that I claim the above I have hereunto subscribed my namein the presence Witnesses GEORGE It. PORTER, H. J. ENNIs.
